Description

Technical Field

[0001] The utility model relates to the technical field of elastic cords, in particular to a strong elastic cord. Background Art

[0002] Elastic cord is also known as elastic cord, rubber cord, rubber cord, rubber cord. Elastic cord is an indispensable item in people's daily life, such as hair rope, elastic band, cuff rope, bandage, etc. Elastic cord has a wide range of uses, including clothing, construction, transportation equipment, binding, sports equipment, etc. In order to ensure the elastic strength of the elastic cord, a strong elastic cord is provided, such as an elastic cord with application number "CN202021549099.8", including an outer skin part and an inner core part, the outer skin part is woven by elastic material and chemical fiber and / or cotton yarn, wherein the elastic material is the warp, the chemical fiber and / or cotton yarn is the weft, the inner core part core line is composed of chemical fiber, and the outer skin part wraps the inner core part to form a spherical part connected in series and a structure of alternating intervals of the straight part. The elastic cord provided by the utility model has a simple structure, beautiful appearance, high elasticity, and a long service life. The utility model has a long service life, and the service life is more than 3 times that of an ordinary elastic cord. Some common elastic cords have an outer skin made of woven chemical fiber and an elastic product as the core. Once the core loses its elasticity or breaks, the life of the entire elastic cord is over. The outer skin of the utility model is made of several elastic products as warp threads and woven with chemical fiber as weft threads. There are many elastic warp threads, which will not break at once under the action of sharp objects or human damage. If one elastic warp thread breaks occasionally, the utility model can still be used normally. The core thread composed of several chemical fiber products of the utility model is difficult to break.

[0003] Elastic ropes are widely used in clothing, construction, transportation equipment, binding, sports equipment, etc. At present, elastic ropes are composed of outer skin and inner core. The outer skin material is mostly made of polyester yarn, nylon yarn, polyester-cotton, pure cotton, high-elastic yarn, etc., and the inner part is latex yarn. Due to its material limitations, it is generally used in scenes with small tension.

[0004] However, the existing elastic cord has average elasticity and cannot withstand large pulling force, which in turn affects the service life of the elastic cord. If a larger elastic force is required, the diameter of the elastic cord needs to be increased, but this results in a larger weight and occupies more space, which cannot meet people's usage needs. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a strong elastic cord, which solves the problem that the existing elastic cord has average elasticity and cannot resist a large pulling force, thereby affecting the service life of the elastic cord.

[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a strong elastic rope, including an outer shell, a filling layer is arranged inside the outer shell, a first rubber band is arranged inside the filling layer, a plurality of second rubber bands are distributed in an annular manner at equal intervals at the inner edge position of the filling layer, and two first elastic ropes are arranged inside the filling layer.

[0007] Preferably, an elastic layer is provided on the outer side of the outer shell.

[0008] Preferably, a wear-resistant layer is provided on the outer side of the elastic layer.

[0009] Preferably, a plurality of second elastic ropes are arranged on the inner side of the wear-resistant layer and the outer side of the elastic layer.

[0010] Preferably, a plurality of said second elastic cords are equidistantly distributed on the outside of the outer jacket.

[0011] Beneficial Effects

[0012] The utility model provides a strong elastic cord. It has the following beneficial effects: the strong elastic cord improves the tensile resistance of the elastic cord by matching the filling layer, the first elastic cord and the second rubber band, and arranging the rubber band and the elastic cord inside the cord body, thereby solving the problem that the existing elastic cord has a general elastic force and cannot resist a large tensile force, thereby affecting the service life of the elastic cord. Under the same diameter, it can provide a larger elastic force. Compared with the elastic cord in the traditional technology, under the same elastic force, its own weight is lighter and occupies less space.

[0013] Through the coordination between the elastic layer, the wear-resistant layer and the second elastic rope, the wear-resistant effect of the outer side of the rope is improved, and the normal use of the inner elastic rope is prevented from being affected by the wear of the surface. At the same time, the multiple second elastic ropes on the outer side further improve the elasticity of the elastic rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The existing elastic cord has a general elastic force and cannot withstand a large pulling force, thereby affecting the service life of the elastic cord.

[0021] In view of this, a strong elastic rope is provided, which improves the tensile resistance of the elastic rope by cooperating between a filling layer, a first elastic rope and a second rubber band, and arranging structures such as rubber bands and elastic ropes inside the rope body, thereby solving the problem that the existing elastic rope has general elasticity and cannot resist large pulling force, thereby affecting the service life of the elastic rope.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: By Figure 1-4 It can be seen that a strong elastic rope includes a jacket 5. The main material of the jacket 5 is polyester fiber, which has a good tensile effect, but its elastic recovery ability is relatively strong. A filling layer 1 is arranged inside the jacket 5. The main material of the filling layer 1 is synthetic rubber silk. Synthetic rubber, also known as synthetic elastomer, is a highly elastic polymer synthesized by man. It is one of the three major synthetic materials and can be butadiene rubber. Butadiene rubber is the second largest synthetic rubber after styrene-butadiene rubber. Compared with natural rubber and styrene-butadiene rubber, it has excellent cold resistance, wear resistance and elasticity after vulcanization, less heat under dynamic load, good aging resistance, and is easy to be used with natural rubber, chloroprene rubber or nitrile rubber. , butadiene rubber is particularly suitable for manufacturing automobile tires and cold-resistant products, and can also be used to manufacture cushioning materials and various rubber shoes, adhesive tapes, adhesive tapes and sponge rubber, etc., the purpose is to fill the gap position in the jacket 5, the filling layer 1 is provided with a first rubber band 2, the inner edge position of the filling layer 1 is annularly equidistantly distributed with a plurality of second rubber bands 4, and the filling layer 1 is provided with two first elastic cords 3. The main material of the first elastic cord 3 is TPR synthetic rubber, also known as artificial rubber or synthetic rubber. The product has the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, and at the same time has the characteristics of convenient processing and wide processing methods of ordinary plastics;

[0024] In the specific implementation process, it is worth pointing out that the first elastic band 2 is arranged inside the filling layer 1, and the two first elastic ropes 3 are distributed on the upper and lower sides of the first elastic band 2;

[0025] Furthermore, an elastic layer 6 is provided on the outer side of the outer jacket 5;

[0026] In the specific implementation process, it is worth pointing out that the main material of the elastic layer 6 is polyester fiber. Polyester fiber, also known as "polyester", is a synthetic fiber made by chemical polycondensation of organic dibasic acid and diol. It belongs to a kind of polymer compound. The elasticity of polyester fiber comes from the interaction between polyester molecular chains. Under the action of stretching, tearing or twisting, the polyester molecular chain will be deformed by displacement, twisting and stretching, and then return to the original shape and length under the action of restoring force.

[0027] Specifically, when the strong elastic cord is used, the filling layer 1, the first elastic cord 3 and the second rubber band 4 are coordinated and structures such as rubber bands and elastic cords are arranged inside the rope body to improve the tensile strength of the elastic cord, thereby solving the problem that the existing elastic cords have general elasticity and cannot resist large tensile forces, thereby affecting the service life of the elastic cords.

[0028] Embodiment 2: By Figure 1-4 It can be seen that the outer side of the elastic layer 6 is provided with a wear-resistant layer 7;

[0029] In the specific implementation process, it is worth pointing out that the main material of the wear-resistant layer 7 is polyurethane, which is a polymer material with high hardness, good wear resistance and strong toughness. The polyurethane material has excellent elastic memory and high strength;

[0030] Furthermore, a plurality of second elastic cords 8 are arranged on the inner side of the wear-resistant layer 7 and the outer side of the elastic layer 6. The main material of the second elastic cords 8 is TPR synthetic rubber, also known as artificial rubber or synthetic rubber. The product has the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, and at the same time has the characteristics of convenient processing and wide processing methods of ordinary plastics;

[0031] In the specific implementation process, it is worth pointing out that the plurality of second elastic cords 8 increase the elastic force of the elastic cord as a whole;

[0032] Further, a plurality of second elastic cords 8 are equally distributed on the outside of the outer jacket 5;

[0033] In the specific implementation process, it is worth pointing out that the multiple second elastic cords 8 are evenly distributed on the outer side of the outer jacket 5 to ensure uniform distribution of tensile stress;

[0034] Specifically, on the basis of the above-mentioned embodiment 1, the wear resistance of the outer side of the rope is improved through the cooperation between the elastic layer 6, the wear-resistant layer 7 and the second elastic rope 8, so as to avoid the wear of the surface affecting the normal use of the internal elastic rope. At the same time, the multiple second elastic ropes 8 on the outside further improve the elasticity of the elastic rope.
